CABINET-ORGAN.

SPECIFICATION forming part of Letters Patent No. 352,128, dated November9, 1886.

(No modeLl' -ure l is a transverse vertical section ol3 an instrumentembodying my invention. Figs. 2 and 3y are similar views showing`different toxins of devices whereby the swell is operated, and Fig. 4 isa horizontal section of the form shown in Fig. 3.

In the drawings, A represents the top, A the front, A2 the lid, A" theend, and A3 the back, ofthe case ot'a cabinet-organ. In the back, nearthe upper part of the case, is an upright hinged valve, B.- lhe saidvalve B is opened when the organ-lid A is opened, and remains so whilethe instrument is being played, In the drawings vI have illustrated anumber of ways in which it may be operated.

In all of the modifications I have shown the lid as being attached to aswinging frame, C, upon which its inner edge is supported.

In Fig. I a toggle-connection, d d, connects the swinging frame or thelid with the upper edge ofthe swell-valve, the opening of the lid inthis case servingto allow thetop of the valve to open also7 a hook, cl,or equivalent device acting to prevent t-he valve from opening too far.When the lid is closed7itstraightens the toggle and shuts the valve.

In Fig. 2 a straight wire7 e, connects the upper part of the swell withthe swinging fra-me C, at about the middle of the latter. This insuresthe opening ot the valve with the opening ofthe lid, and the closing ofboth simultaneously, also7 the open position being indicated by brokenlines.

In Fig. 3 the valve is opened by the opening ot' the lid, andisconnected thereto as t'ollows: A longitudinal and horizontal lever, h,is stalionarily pivoted at one end by the pivot li', land its oppositeend is connected to the lid or swinging trarne C by the link hz. Thelink or wire It, attached to said lever at a point substantiallymidway-between its'endsextends to the valve, as shown. This constructionresults in the openingI or closing of the lid and valve simultaneouslywhenever the former is moved.

It will be noticed that in all the moditications where the valve isoperated by the lid a differential movement is imparted to the valvefrom that required by the lid. This, however, is a matter ot'discretion.

I elaiint l. The combination, in a cabinet-organ, of the sliding lid A2,the valve B, andthe devices connecting said lid and valve, substantiallyas specified.

2. In a cabinet-organ, the lid and its swinging, frame C, in combinationwith the valve B and the devices connecting said frame to the valve,substantially as specified.

3. In a cabinet-organ, the combination, with a vertical swell-valve, B,of devices for opening and closing the saine and the hook d', forlimiting the opening movement, substan-y tially as specitied.
